DE PERE, WI (WTAQ) - Toxicology results show Denis Bay had high levels of prescription drugs used to treat Schizophrenia and Bipolar Disorder when he shot and killed his family in early February.  De Pere police say they don’t know what Bay’s tolerance level was, and that the drugs but could have played a role in the shooting death of his wife Michele and their two kids, 14-year-old Amanda and 10-year-old Daniel.  De Pere Police Chief Derek Beiderwieden says the drugs may have some affect on judgment when you take more or less of prescribed medication.  Toxicology results show Bay had lethal levels, nearly nine times the normal dose of both medications in his system.  Bay also tested positive for muscle relaxers, three times the normal level.  The prescription drugs could explain his subdued and mellow attitude while talking with a 911 dispatcher informing her that he just shot his family.  While on the phone, Bay took his own life.  Investigators says they found 20 gunshots in his family members, and the one bullet that Bay used on himself.  The final report also tells a story of 14-year-old Amanda telling someone she was afraid of her father because she said he pointed a gun at both her and her mother several times.  Denis and wife Michele were going through a divorce.  Police say Bay was getting kicked out of the house that fateful day and even told dispatchers that his wife Michele was playing head games with him because she took him back, then she moved out, and then kicking him out of the home they shared for years.
